The turntable bearing seat is a kind of large and extra-large bearing seat which can accept comprehensive load and has the characteristics of compact structure, sensitive rotation and convenient maintenance. Where there is a bearing, there must be a support point, the inner support point of the bearing is the shaft, and the outer support is the often said bearing seat.
Since a bearing can be configured with different bearing seats, and conversely a single bearing seat design can accommodate different types of bearings simultaneously, the resulting diversity of bearing seat configurations and variants becomes substantial across industrial applications. Bearing seat specifications are included within the technical documentation of many large foreign bearing manufacturers, who maintain detailed bearing seat type records as part of their product portfolio management. However, the same bearing housing model designation is not marked or documented with identical specifications across different company technical samples and catalogs, reflecting variations in manufacturing standards and regional design practices.
Bearing seat selection represents a critical phase in mechanical design and assembly processes, as the specific requirements governing bearings and their corresponding mounting surfaces vary considerably depending on application parameters, load conditions, and operational environments.
在轴承安裝設計中，根據轴承座的几何形状特征進行分類是一種常见的工程(cheng)實践(jian)，这種分類方法可以帮助工程師(shi)根據不同的機械應用(yong)場景選擇
Outer spherical bearing with seat, also known as bearing unit (SKF). When there is no bearing, it is called the outer spherical bearing seat. The outer spherical bearing seat is divided into 200 series according to the bearing series. The 500 series. The 300 Series. The 600 Series. XOO series; The outer spherical bearing seat is divided into vertical seat (P seat), square seat (F seat), diamond seat (FL seat), round seat (C seat), convex round seat (FC seat), convex square seat (FS seat), dark hole seat (PA seat), hanging seat (FA seat); Integral (i.e., non-separate) vertical bearing housing block with screw-secured bearing box cover. These vertical housings were originally developed as axle boxes for light rail trucks, but can also be used with conventional vertical housings. The non-separated vertical bearing block is more rigid than the separated bearing block, and some can withstand relatively heavy loads. The outer spherical bearing seat also belongs to the integral seat.
2 split bearing seat
Split bearing seat, according to the selection of different bearings and shaft requirements into SN2, 5, 3, 6 series, SNL2, SNL5, SD 2, 5, 3, 6, 3100, 3000, 3200. Bearing seat is divided into: split bearing seat, sliding bearing seat, rolling bearing seat, bearing seat with flange, outer spherical bearing seat, etc.
